Monui

Monui is a regulatory call-report and reconciliation platform for de novo trust banks: FFIEC 041/051 filings in XBRL, SDF, and iXBRL from live Workday Financials and core banking data. Produced by Frontier Foundry; advisory through Virtova.

Monui is a Frontier Foundry product. Virtova is the consulting channel for engagements; both entities share ownership. The public-facing launch is on the Frontier Foundry website in May 2026; early-access engagements run through Virtova in the interim.

The platform is built specifically for de novo trust banks operating under OCC supervision. The pain point Monui addresses is concrete: building the regulatory-filing function from scratch in a new charter, against FFIEC 041/051, without inheriting either the legacy general-ledger discipline of an established bank or the brittle spreadsheet workflows that most trust startups end up improvising. Monui ships with the regulatory schedules, validation logic, and audit-trail discipline already in place.

What it does

Monui automates the daily call-report cycle end-to-end:

Daily extraction. Workday Financials integration via SOAP and REST pulls the live general ledger; core-banking integration via a plugin architecture pulls position and transaction data. First-party core-banking support is for NetXD.

Reconciliation. Real-time variance detection between Workday GL and core banking, with configurable thresholds, runs against every data movement. GAAP sign conventions (debit-normal for assets and expenses, credit-normal for liabilities, equity, and revenue) are applied automatically.

Calculation. A three-layer mapping engine resolves general-ledger accounts to MDRM codes through Excel-based ledger mappings, schedule-to-MDRM resolution, and formula evaluation. FFIEC 041 and 051 schedules (RC, RI, RC-C, RC-D, RC-F, RC-R, HI) are supported with 1,076 MDRM codes for 051 filings.

Validation. Fifty-plus FFIEC validation rules (required-field checks, positive-value checks, calculation checks, range checks, and cross-schedule consistency) run before any filing is generated.

Filing generation. Output in three formats: XBRL instance documents for CDR upload, SDF, and iXBRL HTML viewable directly in a browser.

Forecasting. Quarterly financial forecasting with two methodologies (linear and historical growth) and automated alert detection on variance.

Audit and compliance posture

Monui is built for the regulatory audit cycle from day one rather than retrofitted around it. Every data ingestion operation is logged to an immutable audit trail with SHA-256 checksums and tamper detection. Retention policies meet the seven-plus-year banking compliance baseline. JWT authentication with RSA-256 secures service-to-service communication. CORS allowlists, secret management, and TLS 1.3 are baseline; PII handling includes automatic masking with secure-by-default error responses.

The platform’s audit posture connects to the broader thesis described in Cyber audit in the neural-net era: the next-generation audit layer will consume structured, machine-readable, immutably-logged evidence from operator-side systems. Monui produces that evidence as a first-class output of its regulatory workflow, not as a downstream export.

Architecture and operations

Monui ships as a microservice architecture: nine systemd services, PostgreSQL for data, Redis for caching and queues, MinIO for files, Prometheus and Grafana for monitoring, and an interactive Blueprint.js dashboard with seven tabs wired to real API data. Multi-tenant operation supports a bank selector for switching between live and demo environments. Air-gapped install is supported. Rust binaries are pre-built for Linux x86_64 and ARM64 and macOS Intel and Apple Silicon, with sub-50-millisecond service startup.

Engagement and access

Monui early-access engagements are run through Virtova as design-partner relationships in advance of the May 2026 Frontier Foundry public launch. Partners get the platform deployed against their actual Workday and core-banking environment, working sessions on the regulatory mapping calibrated to their charter, and direct input on the platform’s roadmap. The cohort is shaped around de novo trust banks at, near, or shortly after charter approval.

Most early-access conversations start with a 30-minute discovery call. Bring the charter status, the Workday and core-banking footprint, and the timeline to first regulatory filing; we will tell you whether Monui is a fit and what the design-partner engagement looks like.

"Trust banks need to file. The system that produces the filing is also the system that defines what the auditor sees. Monui is built so the answer to both questions is the same machine-readable evidence — immutably logged, deterministically derived, and ready before the cycle closes."

Frequently asked

What is Monui?
Monui is a regulatory call-report system built for de novo trust banks under OCC supervision. It generates FFIEC 041 and 051 filings in XBRL, SDF, and iXBRL from live Workday Financials and core banking data, with daily extraction, reconciliation, calculation, validation, and quarterly forecasting. The system runs as a microservice architecture with an immutable audit trail across every data movement.
Which regulatory filings does Monui produce?
Monui implements FFIEC 041 and 051 with seven-plus schedules (RC, RI, RC-C, RC-D, RC-F, RC-R, HI) plus 1,076 MDRM codes for 051 filings. Output is available in three formats: XBRL instance documents for CDR submission, SDF for upload workflows, and iXBRL inline-XBRL HTML viewable directly in a browser. Validation runs against 50+ FFIEC rules covering required, positive, calculation, range, and cross-schedule checks.
How does Monui integrate with Workday and core banking?
Monui integrates with Workday Financials via SOAP and REST: WID resolution through Get_Ledger_Account_Summary, balance aggregation through Get_Journals, and WS-Security authentication. Core-banking integration uses a plugin architecture, with first-party support for NetXD. The mapping engine is three-layer (GL → MDRM, schedule → MDRM, formula evaluation) and ingests Excel-based ledger mappings.
What audit and compliance posture does Monui ship with?
Monui is built for the regulatory audit cycle from day one. Every data ingestion operation is logged to an immutable audit trail with SHA-256 checksums and tamper detection. Retention policies meet the seven-plus-year banking compliance baseline. PII handling includes automatic masking and secure-by-default error responses. The platform tracks all API calls, data processing, and system operations for downstream supervisory review.
When is Monui publicly available?
Monui is a Frontier Foundry product. The public-facing launch is on the Frontier Foundry website in May 2026, with early-access engagements running through Virtova in the interim. Virtova is the consulting channel for the platform; Frontier Foundry is the product entity. Both entities share ownership.
